what we do know is that our bodies all react differently to different medications. Some have said MTX works others like yourself it didnt work. Same goes for all the biologics. We also know taking any drug will have side effects in most people. As Newton said "for every action is a reaction". I think keeping the PMR from restarting is the key while trying to taper. If one of the biologics helps with that then your doing the right thing. We also know nothing helps your cortisol restart. You still have to go slow and keep trying to stimulate your pituitary.
